The specifications of a hard drive's type, capacity, and speed vary widely based on the model. Common types include HDD (Hard Disk Drive) and SSD (Solid State Drive), with capacities ranging from 128 GB to several terabytes (TB). Speed is typically measured in RPM for HDDs, commonly around 5400 to 7200 RPM, while SSDs offer much faster data transfer rates, often exceeding 500 MB/s to several GB/s, depending on the interface (e.g., SATA, NVMe).
